To all whom it may concern:

,Be i vknown that-I, FRANK J. Cook, citi-- zen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and use ful Improvements in Electrical Heaters, ofwhich the following is a specification.

This application relates to. electrical heaters,.and the inventionconsists in a heater adapted especially to power driven machinescarryingthe requisite equipment and serving as a footrest and warmer ,or heater,all substantially as shown and described and particularly pointed out inthe claims.

In the accompanying drawings, Figure 1 is a perspective view of aportion of an automobile body equipped with one of my newand improvedheaters. Fig. 2 is a lan view of the heater alone and enlarge ascompared with Fig. 1, and showing also a a portion of the immediatesupport or. shield thereon, the parts being broken'aw'ay at the Fig. 3is a side elevation ofthe heater and thecoupling connections at itsmiddle.

ends and also broken away at the middle'and showing a portion of thefoot rest or shield thereon. Fig. 4 is a cross section on'line 4-4, Fig.3.

The heater as thus shown is especially intended for power drivenmachines or cars having an electrical installation of sufficient currentto sustain heat in the heating element, whetherthe car be of theelectrical or explosive or other type. In fact. the heater might haveother uses than such as would limit it to a car or vehicle withoutdeparting from the spirit and scope of the invention. It is, however, ofespecial utility in a car when secured to the floor at the front of theseat as it serves both as a foot rest and heater in this relation andposition.

Now, referring to Figs. 3 and 4, especially, it will be seen that theheating element It is shown as of hexagonal shape in cross section andas having the electrical coil or requisite stabilityand consistency, andcon- 7 nections are made with said wire by the cables 0. The shaping ofthe elemenbwith a series of. fiat sides is material because it enablessaid sides to be overlaid with a nonconducting substance, as strips 2 ofmica, which adhere to the body of the heater and serve as insulation andas means to strengthen and uphold the composition. The said conductingcables 0 are shown as inclosed in or threaded through suitable couplingsand tubes d at the ends of the tube or 'pipe 4 which carries the saidheater and which are sleeved within or upon the ends of the saidinclosing tube or pipe. The said heater is supported upon the bottomofsaid tube without other insulation, in this instance, than the micastrips on the side of the heater, but of course insulation could beprovided if found necessary. The elbows c1 of the said coupling areremovably secured in the tube 4 by the set screws 8, which also supportthe guard, shield or rest 8, and the sai .4 as thus constructed asuiiicient and suitable rest for the feet, but since the air outletopenings in its top are deemed essential and the placing of'the feetthereon would inevitably lead to the accummulation of dirt in the saidpipe or tube, even with the relatively larger openings or slots 6 "inthe bottom to clear the tube, I have affixed a combined rest and guardor shield 8 upon the said pipe, as seen especially in Fig. 4. To theseends, also, the said guard is curved .or convex in cross section and hassutlicient width to extend laterally on both sides beyond the pipe 4 soas to come into effective shielding relation thereto and the screws 8 ateach end serve also to fasten said guard and rest in place. Suitablesleeves or spools 10 are employed between said guard and tube to affordsupports for the guard. The device as a whole constitutes an article ofmanufacture and sale, and as such is variously attachable as well asseparable -into parts. The said cables 0 in addition to carrying thewire connections for the wire coil of the heater are atiixed to thebottom of the supporting tube 4 by screws or bolts 0, Fig. 3, so thatany pull on the cables will come on the said bolts andnot upon theterminals of the heater. As shown herein the elbow couplingsd and thecables therein are extended beneath the floor f of the car.

The heater k is a composite made up of suitably refined or pulverizedsoap stone having a proportion of gypsum or plaster.

of Paris, or its equivalent as a binder, inorporated therewlth so as tomake a solid embodiment which will not break down nor crumble under anyconditions of service.

If no top perforations were used in the .tube 4 the shield or guard 8might possibly be omitted as the said tube is considerably larger incross section than the-heater and the imparted heat would not ordinarilymake the tube sohot as t'o burn the shoe. However, the said shield orard is deemed essential as a portion of the invention.
